Question

Keri walks her dog every morning. The length of the walk is 0.55 kilometer on each weekday. On each weekend day the walk is 1.4 times as long as a walk on a weekday. How many kilometers does Keri walk in one week?

Answer 1

Monday through Friday total walks = 5(.55) = 2.75 km

on Saturday & Sunday total walks = 2(1.4)(.55) = 2.8(.55)= 1.54 km

total for all week = 2.75+1.54 = 4.29 km
